BrewBuilt IceMaster Max 4 - Page 3

The ice bath temperature controller (found on the opposite side of the pump controllers, just
below the upper vents) has several functions to help maintain ideal conditions to control your
fermentations.

THE DESIRED TEMPERATURE SETTING
THE +/- TEMPERATURE RANGE
IceMaster will cycle on/o to keep its
temperature within the set range of the
set temperature - example: if you set the
temperature at 5°C with +/- 0.5 the unit will
cycle on/o over a 1°C range at 4.5°C and
5.5°C. The lowest setting is 0.3°C.
COMPRESSOR DELAY TIME IN MINUTES
This feature protects the unit from turning on/
o too quickly, and potentially damaging the
compressor. The range is from 1-10 minutes
with the default set at 3.
CALIBRATES THE ICEMASTER AGAINST AN
ACCURATE THERMOMETER
Generally, the unit does not need any
additional calibration. However, to nd
the correct adjustment - place an accurate
thermometer in the unit and compare against
the controller readout. If needed, set the
calibration on the controller +/- by the number
of degrees it is o. This will ensure the unit is
adjusting to your desired temperature properly.

every 6 months.
IceMaster does not turn on
IceMaster does not seem
cold enough
IceMaster shuts o/on
too oen
IceMaster is always on
IceMaster seems to make
too much noise
Check temperature setting by placing a thermometer inside reservoir.
Check aer 30 minutes & compare against set unit temperature.
Calibrate with F4 function on controller as needed.
Check set temperature range. Adjust F2 function on controller
to a higher range.
Ambient room temperature is too high, so unit is working harder
to cool to set temperature.
Humming is normal and gurgling sounds are caused by cooling
liquid used by the unit. The unit may not be not level.
Check circuit breaker or fuse ; Check plugs.
